Oscar favorite Octavia Spencer has joined the cast of Snow Piercer for Korean director Joon-ho Bong.

The story is set in an alternate future, where a failed experiment to stop global warming results in a new Ice Age. The frigid climate has killed off all life on Earth, except for the passengers aboard a train dubbed Snow Piercer. A class system develops among the passengers on this train, which ignites a revolt. Octavia Spencer will portray a passenger who joins the uprising in order to save her son. Chris Evans, Tilda Swinton, Jamie Bell, John Hurt, and Kang-ho Song also star.

Joon-ho Bong is directing Snow Piercer from his own original script. Chan-wook Park and Dooho Choi will produce.
